Description

Technical Field

[0001] The utility model relates to the technical field of welding splitters, in particular to a deep cavity welding splitter for multi-wire welding. Background Art

[0002] The existing terahertz transmission rate is more than 100 times that of 5G, reaching: 300Gbit / s to 1Tbit / s; the delay is less than one thousandth of 5G, reaching the nanosecond level. At the same time, in order to achieve a transmission effect of several hundred Gbit / s to Tbit / s, silicon photonic transmission modules are now a mature signal transmission method, and their transmission rate has been commercialized to less than 500Gbit / s.

[0003] Due to the extremely short wavelength of terahertz frequencies, chip packaging requires extremely short arcs and minimal spacing to minimize parasitic parameters of the gold wire arcs. The high transmission rates of silicon photonics transmission modules, due to the optical mode transmitting light signals, require extremely high bonding arc height and arc consistency.

[0004] With traditional splitting tools, one wire is passed through each splitting tool, and the arc length and arc height are adjusted between the wires by a bonding machine. Such multiple processes make it difficult for the bonding height and arc consistency to meet the bonding consistency requirements of terahertz and silicon photonics.

[0005] In view of this, a deep cavity welding whet for multi-wire welding is urgently needed to solve the above problems. Utility Model Content

[0027] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] like Figure 1-4 The present invention provides a kind of deep cavity welding splitting knife for multi-wire welding, comprising: a knife body, the knife body comprising a knife head 1 and a knife body 2, the knife body 2 is provided with a wire threading hole 3, the wire threading hole 3 extends from the end of the knife body 2 away from the knife head 1 to the end of the knife body 2 close to the knife head 1, and the end of the knife head 1 away from the knife body 2 is provided with a knife tip 4; a guide hole 5 is provided on the knife head 1, the guide hole 5 extends from one side of the wire threading hole 3 to the side of the knife tip 4, and a wire outlet hole 6 is provided on the side of the guide hole 5 close to the knife tip 4, and a plurality of wire outlet holes 6 are provided. When in use, a plurality of wires are passed through the wire threading hole 3 and the guide hole 5 in turn, and a plurality of wires are respectively passed through the plurality of wire outlet holes 6, and the plurality of wires are bonded and welded at the same time through the knife tip 4, ensuring the consistency of the arc length and arc height of the welding of the plurality of wires, and the optimal arrangement of the plurality of wire outlet holes 6 is a linear distribution, and the specific number of the wire outlet holes 6 is set according to actual use requirements. In this embodiment, three wire outlet holes 6 are selected.

[0031] like Figure 2 and Figure 4As shown, in order to facilitate the delivery of the wire passing through the wire hole 3 to the guide hole 5, a guide groove 7 is provided on one side of the cutter head 1, and the guide groove 7 extends from the wire outlet of the wire hole 3 to the wire inlet of the guide hole 5. In this way, the wire passing through the wire hole 3 is guided by the guide groove 7 and finally passes into the guide hole 5. In order to avoid interference between multiple wires, the guide groove 7 is composed of multiple guide channels arranged in parallel. A number of dividing ribs consistent with the extension direction of the guide groove 7 are provided in the guide groove 7, and a guide channel is formed between two adjacent dividing ribs, and multiple wire outlet holes 6 correspond one to one with the multiple guide channels. In this way, multiple wires are placed in multiple guide channels respectively, and finally pass through the corresponding wire outlet holes 6 without interfering with each other, thereby ensuring the smoothness of wire supply.

[0032] like Figure 2 and Figure 4 As shown, in order to facilitate the lead-out of the wire, the end face of the blade tip 4 is provided with a forming groove 8, and the outlet of the wire outlet hole 6 is located in the forming groove 8. In order to ensure the consistency of the arch arc forming during welding, the end face of the blade tip 4 is provided with a welding groove 9 at one end away from the guide hole 5. The welding groove 9 is arranged parallel to the forming groove 8. Similarly, the arrangement direction of the multiple wire outlet holes 6 is also parallel to the extension direction of the welding groove 9.

[0033] like Figure 1 and Figure 3 As shown, in order to reduce the interference with other components during the processing, an avoidance plane 10 is provided inwardly on the ring side of the end of the blade body 2 close to the blade head 1, and avoidance slopes 11 are provided on both sides of the avoidance plane 10. The two avoidance slopes 11 extend from the side away from the blade head 1 to the side close to the blade head 1 and to the side close to each other. In this way, one end of the blade body 2 is converged toward one end of the blade head 1, reducing the volume of the blade body 2 close to the end of the blade head 1 and reducing interference during processing.

[0034] Further optimization is that the material of the blade can be tungsten carbide, titanium carbide, ceramic or ceramic metal, among which tungsten carbide has strong resistance to breakage; titanium carbide has better performance in transmitting ultrasonic waves; and ceramics are smoother, denser, non-porous and chemically stable. In addition, the thermal conductivity of ceramic splitting knives is low, and the splitting knives themselves do not need to be heated.

[0035] In summary, when in use, multiple wires are passed through the wire threading hole 3 and the guide hole 5 in turn, and multiple wires are respectively passed through the multiple wire outlet holes 6. The multiple wires are bonded and welded at the same time through the knife tip 4 to ensure the consistency of the arc length and arc height of the welding of multiple wires.

[0036] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations directly derived or imagined by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the scope of protection of the present invention.
